Darren Mark and Dan Barfod have been awarded £300k by the Natural Environment Research Council for development of a SELFRAG facility at SUERC. The facility will be open to collaborative and commercial use from late 2020. For initial inquiries please contact

Key Features

  • SELFRAG is selective fragmentation using high voltage pulsed power A 'bolt of lightening' is passed through the sample causing it to shatter along the boundaries of different material phases.

  • Preferentially reduces mixtures to individual components before reducing the particle size of a pure component. inclusions are liberated keeping the host material large.

  • For highly crystalline material the impurities will be liberated first whilst keeping the size of the pure quartz crystals large.

  • Separate zircons, diamonds, gemstones and industrial minerals from the host rock.

  • Separate recycling and e-waste into the individual components.
